A lock nut straight-through end pipe joint is mounted at each joint of the tracheae and each part. The pressure-reducing valve is a direct-acting pressure-reducing valve, an inlet of the pressure-reducing valve is connected with the tracheae at the side near the gas source, and an outlet of the pressure-reducing valve is connected with the tracheae at the side near the air hole. The air impermeability detection apparatus of the sealing device is simple in structure and easy to assemble and disassemble. By using the air impermeability detection apparatus of the sealing device to detect air impermeability of a low pressure sealing device or a container, the air impermeability can be pre-detected before a device is mounted, loss caused by poor air impermeability can be prevented, and the sealing device can also be detected regularly, achieving real-time maintenance and ensuring normal operation of the device.
Description
Technical field
The utility model relates to a kind of detection and surveys device, specifically a kind of device of the sealing property for detection of mortgage airtight container or device.
Background technology
The function of vertical roll grinder Burnisher apparatus is that the lumped coal abrasive lapping is become to the fine particle shape, in order to enter dust-precipitator through the housing outlet conduit together with steering current.
One of design feature of vertical roll grinder Burnisher apparatus is that its inside forms a relative confined space by parts such as wheel hub, oil sealing, end caps; store a certain amount of lubricating oil in this space; form lubrication protection when bearing working, guarantee usability and the life-span of bearing.When if the sealing property of Burnisher apparatus does not meet design requirement, Burnisher apparatus leakage of oil after there will be vertical roll grinder equipment to install, the equipment part of causing reprocess, install and go into operation delay, the lubricating oil product waste, production environment is polluted and because repeatedly loading and unloading the problems such as damage that cause the Burnisher apparatus oil sealing.Therefore, in actual use, need regularly to it, to carry out the impermeability detection, and existing air-tightness detection device mostly is and designs for high pressure seal, the impermeability detection of inapplicable and this low pressure seal device.
The utility model content
The utility model is the problem of revealing for low pressure seal device oil product, and a kind of device that can be detected low pressure seal device air-tightness is provided.
Realize that above-mentioned purpose by the following technical solutions: a kind of packoff air-tightness detection device, comprise source of the gas, tracheae and tensimeter, one end of described tracheae is communicated with a pore of packoff by plug screw, cutting ferrule stop valve and reduction valve are housed on tracheae successively, and the other end of tracheae is connected with source of the gas; Another pore of packoff is connected with tensimeter with tracheae by plug screw.
Locknut formula directintermination pipe adapter all is equipped with in tracheae and each parts junction.
Reduction valve is direct acting pressure, and the input port of its this reduction valve is connected with source of the gas side tracheae, and the delivery outlet of reduction valve is connected with pore side tracheae.
Tracheae is the polyamide tracheae.
The utility model is simple in structure, easy accessibility, low pressure seal device or container are carried out to the impermeability detection, not only can before installing, equipment carry out preliminary examination to its air-tightness, avoid the loss caused because air-tightness is poor, can also regularly detect packoff, realize real-time servicing, guarantee the equipment normal operation.
The accompanying drawing explanation
Fig. 1 is that the utility model is used view.
In figure: tensimeter 1, plug screw 2, tracheae 3, cutting ferrule stop valve 4, reduction valve 5, source of the gas 6, oil sealing 7.
Embodiment
Below in conjunction with drawings and Examples to this novel being described further.
This pick-up unit disclosed in the utility model is that the air-tightness for the low pressure seal device is detected.
This pick-up unit comprises tensimeter 1, plug screw 2, tracheae 3, cutting ferrule stop valve 4, reduction valve 5, source of the gas 6.Wherein an end of tracheae is communicated with a pore of packoff by plug screw, and the other end of tracheae is connected with source of the gas, and cutting ferrule stop valve and reduction valve also are installed on tracheae successively.Tensimeter is connected with another pore of packoff with plug screw by tracheae.
For guaranteeing the accuracy detected, tracheae all is connected with locknut formula directintermination pipe adapter with cutting ferrule stop valve, reduction valve and source of the gas.Wherein reduction valve is direct acting pressure, and its input port is connected with the tracheae of source of the gas side, and its delivery outlet is connected with the tracheae of pore side, can not connect anti-.
Tracheae is the polyamide tracheae, the pressurized air that the gas that source of the gas provides is clean dried, nitrogen or other inert gases, and gas temperature English testing environment temperature is similar.
See accompanying drawing 1, the roll-type coal mill Burnisher apparatus of take describes as example.One end of Burnisher apparatus oil sealing 7 is standing upward, the other end need reserve certain detection space, check on Burnisher apparatus everywhere whether good seal of oilhole, sealing plug and sealing air velar plate, the rotation of dish action roller shaft, the roller core end face is had to three G1 of place 1/2 oilholes, wherein a place blocks with sealing plug, other two G1 of place 1/2 oilholes: a plug screw 2 that connects the utility model device air feed interface; Another Bonding pressure table 1, change and carry out the detection of Burnisher apparatus sealing property by manometric indicating value.
First this pick-up unit is assembled, is being detected according to following steps:
The plug screw 2 that 1, will connect tracheae is communicated with one of them pore, opens gas source switch, checks the aeration of Burnisher apparatus, and the output pressure of regulating direct acting pressure is 0.1MPa;
2, close source of the gas, at another G1 1/2 oilhole, load onto tensimeter;
3, open gas source switch, observe tensimeter:
If 1. tensimeter is without voltage rise, there is serious leak site in Burnisher apparatus, with liquid soap spraying (or lubricating oil oil immersion), assembles position everywhere, check and whether have bubble to occur, determine leak site, check to analyze and reveal reason and repaired, again do experiment again after having repaired;
2. after pressure reaches 0.1 MPa, first close cutting ferrule stop valve, then close source of the gas, carry out pressurize, dwell time 30min;
3. within the dwell time, observing tensimeter pressure changes, if pressure drop surpasses 20%, open the cover stop valve, open gas source switch, with liquid soap, spray (or lubricating oil oil immersion) binding site everywhere, check and whether have bubble to occur, determine leak site, check to analyze and reveal reason and repaired, again test again after having repaired;
4. within the dwell time, observe tensimeter pressure and change, if pressure drop does not surpass 20%, mean that the Burnisher apparatus sealing property is qualified;
5. open the cutting ferrule stop valve release, after the Burnisher apparatus internal and external pressure balance, the air-tightness detection device part is pulled down, and three G1 of place 1/2 oilholes are blocked with sealing plug;
The impermeability of 4, carrying out as stated above all the other Burnisher apparatus detects, and after all Burnisher apparatus impermeability have detected, keeping is pulled down and improved to above-mentioned Burnisher apparatus air-tightness detection device.
